To allwhcm it may coo cam Be it lmown that-I; I. WOHL, cititen of the free-city of Danzig, at -Danzig-Langfulir, Gennany, have invented certain new and useful Improvements in Exosives, (for which I havogfiled an appliesthe following is a spcclfiwtlon.

" gustible or oxidizablc substance the roducts The present invention to new exlosives which contain fasca'bonaceons, comof polymerization of ac yleilo- Suc insoluble :i nd high molecular products 0 polymer ylene. By'the action ,of on runs oxide on acetylene at a temperature 0 about 230 as,

960 C. it is possible by a continued treatment with acetylene to obtain compounds with only 02-03% copper if there is suificient space for allow ng the new formed products of polymerization to spread without choking the spuce. The product is therefore no definite copper compound of acetylcne, but lather essentially a hydrocarbon, namely a product of polymerization odtlme acetylene, corresponding very nearly tothe form'ule.( )n.

All those products are well lmown. and form no part of the invention, theessential feature of, which consists in the application of those solid high molecular polymerized products of acetylene for the preparation of explosives in combination with oxygen-carriers or combustion-supporters li crating oxygen during the detonation.

i have found, that those solid high molecular products of polymerization of the acetylene which may betermed polymerized acetylene are especially suitable for serving as combustible matter for explosive mixtures, to be applied for blasting, shooting, filling shells, cartridges and the like.

The explosives according to the present invention therefore consist of mixtures of organic or inorganic compounds which libergite oxygen during detonation with the said polymerized acetylene and other combustible substances. ifso desired.

One explosive according to the present invention consists of polymerized acetylene end nitroglycerine, for instance, of one part of and; rum; .as u iuaanxea m,,l,;.aa; set-else; assess.

Another explosive according to my inventionconsists of a mixture of a polymerized acetylene with nitrates, chlorates onprchlo- "rates and is a good substitute for gun-powder, blasting powder and the like. In ex plosives ofthat class the polymerized acct lens is a. substitute for finely divided car- Such oxplosive may consist, as an example, of po ymerized acetylene, sulphur and potassium nitrate. One can also have solutions, preferably aqueous, of oxidizing salts as, for instance, potassium nitrate, ammonium nitrate, chlorates or perchlolhtes absorbed by the polymerized acetylene. The mixture may be dried at low temperatures. In order to facilitate the absorption of the solutions by the polymerized acetylene one may carry out the absorption under :diminished pressure.

The absorption. of the ueous solution may be facilltatedby the a dition of substances favorizing the wetting of solid substances by li uids, as, for instance, solutions of son 5 inc uding resin, soaps, ethyl alcohol, .urkey red oil, yridine or generally tor bases, mixtures of phenols and soaps, etc. The said substances may be added to the aqueous solutions tobe absorbed or the polymerized acetylene may be moistened with the said substances before the absor tion of the solutions of the oxidizing substances and then pressed out; about 10 parts by weight of aqueous saline solutions can be absorbed by 1 part by weight of the polyml'l'lZB l acetylene at ordinary temperatures. 1 may use, for instance, 0.1O2% of Turkey red oil calculated to the said aqueous solu tion. I may introduce alcohol vapors in the polymerized acetylene and then allow the aqueous solutions to be absorbed.

A further new explosive of the same kind can be produced by adding liquefied air to the polymerized acetylene in suitable proportions. A mixture of one part by weight of polymerized acetylene with 16 parts by weight or more of liquefied air has been found very suitable. Those mix ures are very good explosives, because the polymerized product is a carbon carrier of high calorific value. The explosive must be prepared in situ just before its application.

For blasting with liquefied air the flocculent products of polymerization are well suited whichalso possess a high absorbing apacity. They can be produced by polymerizing a small amount of acetylene in a large space.

may also add to the mixtures of the polymerized acetylene and the oxidizing substances solid or liquid carbonaceous substances; for instance, wood carbon, saw-dust, wood petroleum, tar oils, naphthalene and so forth. I can obtain ammonium nitrate, chlorate or erchlo ate powder by using the polymerize acetylene as carbon. carrier 1 ,eoepss alone or besides other carbonaceous substances.

Having now described my invention and the manner of carrying it out I declare what I claim and desire to secure by Letters Patent is:-

1. An explosive comprising a mixture of solid high molecular polymerized acetylene and a combustion supporter liberating oxygen durin detonation.

2. An exp osive containing, solid high molecular polymerized acetylene and solid combustion-supporters liberating oxygen during the detonation, substantially as described.

3. An explosivecontaining solid high molecular polymerized acetylene and perchlorates, substantially as described.

4. An explosive containing solid high molecular polymerized acetylene of a flocculent character and a combustion supporter liberating oxygen during detonation, substunt-hilly as described.

5. An explosive containing solid high molecular polymerized acetylene, combustion-supporters, liberating oxygen during the detonation and carbonaceous matter substantially as described.

in testimony whereof I afiix my signature in presence of two witnesses.
